the HTML.ERB like this, and then it generate a html, it. the <table>
indent not it shoud be, and the second <tr> also indent not the noraml.
why it generate a html like that?
second, I think everytme I should check empty object like object.blank?
and then iterate the object is very ugly. how to change this ugly
behavior?
==========
<h1>h1_title</h1>
<% unless @obs.blank? -%>
<table border="0" cellspacing="0" class="normal_table">
<tr>
<th>data</th>
<th>state</th>
<th>number</th>
<th>operation</th>
</tr>
<% @obs.each do |ob| -%>
<tr>
<td><%= ob.created_at %></td>
<td><%= ob.state %></td>
<td class="info">ob.number</td>
<td>ob.operation</td>
</tr>
<% end -%>
</table>
<% end -%>
=============================================
<h1>h1_title</h1>
<table border="0" cellspacing="0" class="normal_table">
<tr>
<th>data</th>
<th>state</th>
<th>number</th>
<th>operation</th>
</tr>
<tr>
<td>2010-07-27</td>
<td>initialize</td>
<td class="info">1</td>
<td>un_done</td>
</tr>
</table>
